Hell is a tough doctrine.
In his book the Problem of Pain, CS Lewis sums up what I think many would agree with: “There is no doctrine which I would more willingly remove from Christianity than this, if it lay in my power. But it has the full support of Scripture and, specially, of our Lord’s own words; it has always been held by Christendom; and it has the support of reason.”
We’re fine with the idea of a loving God, but we’re less accepting of a God who judges.
With the idea of hell, It can seem unfair. We can feel tempted to justify why hell doesn’t exist. Or maybe we think that hell is really just for people who are really, really bad.
